1Z0-1127-25 OCI Generative AI Service Practice Question
A team wants to use OCI Generative AI Agents to build a RAG system that answers questions from documents stored in OCI Object Storage. What must they create first?
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
A knowledge base that indexes the documents from Object Storage
The agent requires a knowledge base that is connected to the data source. Directly creating a session without a knowledge base and agent will fail.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
A knowledge base that indexes the documents from Object Storage
Why this is correct
The knowledge base links the data source to the agent and enables retrieval.
- ✗
A fine-tuned model on the documents
Why it's wrong here
RAG does not require fine-tuning; the base model retrieves from the knowledge base.
- ✗
A dedicated AI cluster for the agent
Why it's wrong here
Agents run on managed infrastructure; a dedicated cluster is optional but not required.
- ✗
An OCI Functions endpoint to process documents
Why it's wrong here
Functions are not required; the agent service handles document ingestion.
